Ubu Roi has posted a very tasty 1984 concert by the Mal Waldron Quintet, featuring Waldron on piano, Woody Shaw on trumpet, Charlie Rouse on tenor sax, Reggie Workman on bass, and Ed Blackwell on drums. Hard to go wrong with a lineup like that... I have at least two Waldron Night Lights shows I hope to do in the next year or so; he was a man of quiet accomplishment.
Update: Ubu says it's now up on dime.
